Gradient Boosting

Gradient Boosting is a powerful ensemble machine learning technique used for both classification and regression tasks. It is a combination of multiple weak learners, typically decision trees, that are sequentially added to improve the overall predictive performance. Gradient Boosting works by iteratively training new models on the residuals of previous models, reducing the loss and boosting the predictive accuracy.
